GEARING.

Original application filed September 21, 1911, Seria November 13, 1911.

To all whom it may concern Be it known that I, GEORGE WV. SWIFT, Jr., of Bordentown, in the State of New Jersey, have invented a certain new and useful Improvement in Gearing, whereof the following is a specification, reference being had to the accompanying drawings.

This application is a division of my application Serial #650,492, filed September 21, 1911 for Letters Patent of the United States for an improvement in mechanism for making paper receptacles.

It is the object of my invention to provide mechanism whereby a shaft, for instance the vertical shaft which carries a circular series of paper receptacle holders in the mechanism aforesaid, is positively intermittently turned, stopped, and held temporarlly stationary after each turning movement, and my invention includes the various novel features of construction and arrangement hereinafter described, comprising the com bination with a driven shaft; of continuously rotary means arranged to turn said shaft, including a crank having a wrist pin roller; a disk on said shaft, having four radial slots adapted to be successively engaged by said wrist pin roller; four stop rollers in a circular series on said disk, concentric with said axis; a stop disk on the axis of said crank, having a circular arc channel concentric with said crank axis and of such circumferential extent as to successively engage said stop rollers when said radially slotted disk is released by said wrist pin roller; whereby said driven shaft is positively intermittently turned quarter revolutions, stopped, and held temporarlly stationary after each quarter revolution.

In said drawings; Figure I is a fragmentary plan view of a machine conveniently embodying my invention. Fig. II is a fragmentary elevation of the right hand side of said machine as indicated in Fig. I.

In said figures; the mechanism is supported on the frame 260 and is driven by suitable gearing engaging the gear 299 on the shaft 300 mounted in the frame bracket 301 and carrying the continuously rotary driven element including the crank arm 302 having the wrist pin roller 303 arranged to successively engage the four radial slots 30a in the intermittently driven element including the disk 305 fixed on the vertical driven shaft 86, which latter supports the circular series of Specification of Letters Patent.

holders for the paper receptacles in the ma chine described in my original application aforesaid.

It is to be understood that the arrangement above described is such that by the continuous rotation of said crank 302, said disk 305 is automatically engaged and released by said roller 303, being thus intermittently turned quarter revolutions and left in the position shown in Fig. I. In order to stop and hold said disk 305after each quarter revolution thereof I provide stop mechanism including the four rollers 307 on said disk, and the channel 308 of the stop disk 309 which is carried by said gear 301 in rigid relation with said crank 302, so as to suc- 'cessively engage said rollers 307.

I do not desire to limit myself to the precise details of construct-ion and arrangement herein set forth as it is obvious that various modifications may be made therein without departing from the essential features of my invention as defined in the appended claims.

I claim 1. In mechanism of the class described, the combination with a driven shaft; of continuously rotary means arranged to turn said shaft, including a crank having a wrist pin roller; a disk on said shaft, having four radial slots adapted to be successively engaged by said wrist pin roller; four stop rollers in a circular series on said disk, concentric with said axis; a stop disk on the axis of said crank, having a circular arc channel concentric with said crank axis and of such circumferential extent as to successively engage said stop rollers when said radially slotted disk is released by said wrist pin roller; whereby said driven shaft is positively intermittently turned quarter revolutions, stopped, and held temporarily stationary after each quarter revolution.

2. In mechanism of the class described, the combination with a driven shaft; of continuously rotary means arranged to turn said shaft, including a crank having a wrist pin roller; a disk on said shaft, having four radial slots adapted to be successively engaged by said wrist pin roller; four stop rollers in a circular series onsaid disk, concentric with said shaft; a stop disk on the axis of said crank, having means arranged to successively engage said stop rollers when said radially slotted disk is released by said wrist pin roller; whereby said driven shaft is positively intermittently turned quarter revolutions, stopped, and held temporarily stationary after, each quarter revolution.

3. In mechanism of the class described, the combination with a driven shaft; of rotary means arranged to turn said shaft, in-

cluding an eccentric wrist pin; a disk on said shaft, having slots adapted to be successively engaged by said wrist pin; stop rollers in a circular series on said disk concentric with said shaft; a. stop disk on the axis of said eccentric, having means arranged to successively engage said stop rollers when said slotted disk is released by said wrist pin; whereby said driven shaft is positively intermittently turned quarter revolutions, stopped, and held stationary after each quarter revolution.

4. In mechanism of the class described, the combination with a driven shaft; of rotary means arranged to turn said shaft, including an eccentric pin; an element on said shaft, having slots adapted to be successively engaged by said pin; stop rollers in a circular series concentric with said shaft; a stop disk on the axis of said eccentric, having means arranged to successively engage said stop rollers when said slotted disk is released by said pin; whereby said driven shaft is positively intermittently turned, stopped, and held stationary after each turning movement.

5. In mechanism of the class described, the combination with a driven shaft; of rotary means arranged to turn said shaft, including an eccentric; an element on said shaft, having slots adapted to be successively engaged by said eccentric; stops carried by said shaft; means carried by said eccentric arranged to successively engage said stops when said shaft is released by said eccentric; whereby, said shaft is positively intermittently turned, stopped, and held stationary after each turning movement.

In testimony whereof, I have hereunto signed my name at Bordentown, New Jersey, this; tenth day of November, 1911.
